I can understand where you're coming from. there are just so many rumors about the cali programs. Here are my insights
1. UCD
Happy residents, nice attendings, hugely trauma heavy with crappy lifestyle. sacramento isn't for everyone, especially if you're considering the other cali programs.
2. UCSF
Same disclaimer as UCSD (didn't rotate). Great OR experience, great academic faculty who are well known and rapidly diminishing malignancy (many of the older guys, including the chairman, are leaving and the new faculty are supposedly much nicer). You do get worked pretty hard though and the ancillary staff is probably the worst among the major cali programs. The residents are happiest when at affiliated hospitals, not at UCSF med center (probably because they operate more with nicer attendings at other hospitals).
San Fran is a great city too.
3. UCI
Lots of OR, nice attendings, nice lifestyle, not trauma heavy. Not the brainiest program and with lesser known attendings. Orange county can be great or boring. this program is a lot like stanford but with a lesser national name (perhaps undeservedly so)
4. Stanford:
I rotated here as well. The residents were quite happy from plentiful OR time, not being trauma heavy, benign staff, and generally easy lifestyle. However, these aren't the sharpest guys in the world. In fact, i was pretty underwhelmed at the lack of brainy-ness from the residents and woeful lack of academic talent in the faculty (only 2 attendings are well-known)
Tons of clinic, average ancillary staff for california, Palo Alto is either great or boring (depending on your preference) and of course no chairman for three years.
Then again, the residents are happy both inside and outside the hospital.
5. UCLA:
From my experience (as a rotator), the rumors about ucla are all TRUE. The residents really don't operate that much.
I saw fellows fighting over cases, leaving the poor R4 holding retractors. The really poor R2 got to write orders. fun.
some of the residents admitted that only half the chiefs could be competent in general ortho private practice. I believe it since I didn't think the chiefs were particularly talented (largely from inexperience) in simple trauma cases. They're all smart guys but i personally would be pretty annoyed and unhappy working hard but not getting the benefits of operative time. While the residents were indeed happy, they were mostly happy only when they left the hospital.
6. UCSD
I didn't rotate here. All I know is from residents at my home institution and from when I interviewed there. The research year comes after your internship and this SUCKS. Even the chairman admits this is the one thing he would change if he could. The faculty say they don't ask the resident's opinion on the research year scheduling because they know the answer already.
I also thought they exaggerated their OR experience and resident camraderie. They seem like a disparate group with often conflicting personalities - with each other and the facult. Considering how small they are, that could be a disaster.
On the other hand, it's probably not as malignant as people say and like UCLA, the residents are very happy when they leave the hospital (it's San Diego after all).
Oh, they have SATURDAY conferences. terrible.
